In the molecule of the title compound, [Cu(NO(3))(2)(C(6)H(6)ClN)(2)], the Cu atom lies on an inversion centre and is six-coordinated by two pyridine N atoms and four nitrate O atoms in trans positions. The nitrate acts as an unsymmetrical bidentate ligand. The coordination geometry is octahedral, with the Cu-N and the two Cu-O distances being 1.9939 (16), 2.0246 (16) and 2.4866 (19) A, respectively. There are five types of C-H.O hydrogen bonds. Two of these generate two-dimensional molecular networks in the direction of the a axis, and the others connect adjacent molecular networks.
